For pawn shops, diamond ring recycling is a very common thing. The diamond recovery of pawn shops mainly depends on 4C standard. At this time, the brand of diamond is not important. As for the price, the pawnshop will look at the type of pawn you choose and the size of the diamond.
If the diamond ring you buy is an international brand, the brand store will recycle your diamond ring, but the store will not give you the matching amount. They will give you jewelry with the same price, such as the same diamond ring or diamond necklace.
